Title: Improvements in four-stroke-cycle internal combustion engines
IPC: F02B75/02
Filed: 1934-05-01
Abstract: 419,258. Four stroke engines; oil engines. MILLER, J., and REBBECK, F. E., c/o Harland & Wolff, Ltd., Belfast. May 1, 1934, No. 13075. [Classes 7 (ii) and 7 (iii).] In an engine having a hollow piston compressing the air charge at its rear side, the compressed charge is admitted to the combustion chamber through a valve 8 seating in the crown of the piston. The exhaust valve 4, or the fuel valve, or starting-air valve, or ignition device, is disposed in the cylinder head in an opening 6, through which access may be had to the valve 8. The hollow piston forms an air reservoir 14 which may extend down into a space 15 in the piston rod. The reservoir 14 communicates by a check valve 22 with the closed end 19 of the cylinder, the latter having one or more suction valves 21. The valve 8 remains closed during the firing stroke, air behind the piston being forced through the valve 22 into the hollow piston. Towards the end of the exhaust stroke, as the cylinder pressure falls, the air pressure within the piston opens the inlet valve 8, which remains open during the suction stroke, further air being forced into the hollow piston. The valve 8 may be automatic or actuated mechanically, either by an extension through the piston rod, or by mechanism extending through the side or bottom of the piston. The various hollow pistons may be connected together by telescopic pipes working in fixed vertical pipes connected to a horizontal manifold.

Abstract: 203,370. Martin, H. E., and Harris, R. A. May 10, 1922. Packeting by wrapping-up.-Relates to apparatus for wrapping caramels, sugar-cubes, &c., and of the kind in which the article is inserted with the paper into a recess. in an intermittentlymoving member, which may be an oscillating arm, and in the folding operations, the final fold is made by the transference of the article into a delivery trough. According to the invention,. end-folders co-operate with the moving member and are held momentarily stationary during the approach of the member to fold in a corner of the projecting ends of the paper. The folders are then moved across the end faces of the package to smooth down the paper. The oscillating arm is specially actuated and the web feed is adjustable. As shown, the paper 1, Fig. 1, isdrawn from a roll beneath a rod 4 drawn downwards by a spring 6 and through a channel guide 7, Figs. 1 and 4. A spindle 7<a> carrying the guide is laterally adjustable by rotation of a milled wheel 9. The paper passes between rollers 11, 12 on shafts 18, 94. The shaft 18 is intermittently rotated by a pawl and ratchet-wheel, the throw of the pawl being adjustable. The roller 12 is pressed by a spring 91 upon the roller 11 and when the pressure is not required the tail 92 of the lever 88 carrying the shaft 94 is engaged by a spring clip 93. Cutters 25, 26 sever a wrapper from the web, and a plunger 46 forces the wrapper and a caramel into a recess 32 in an oscillating arm 27. The hinged cover 33 of the recess is formed with a tail 44 and is opened against the action of a spring 35. The amount by which the recess is opened is adjusted by a screw. The arm 27 is pivoted at 28 and is positively actuated in both directions by cams- 31. By withdrawing the pin 28 the arm may be removed from the machine. The entrance of the caramel and wrapper into the recess folds the wrapper around three sides of the caramel, and, on the descent of the arm, a fixed folder 55 folds up the fourth side. Folders 56, Figs. 1 and 6, remain momentarily stationary during the descent of the arm and tuck in the rear corners of the paper as shown in Fig. 6. They are then caused to move across the end of the article and smooth the paper. Stationary folders 65, 66, Fig. 7, make the next folds and an ejecting plunger 68, actuated by a cam-operated arm 76, forces the caramel and wrapper into a delivery trough 67, folding down the outstanding edge upon the top of the article and leaving triangular tabs. The tabs are folded down by converging passages formed in the lid 69, Fig. 10, of the trough, held in slots 70 by a spring 71. The passages are formed so that one tab is completely folded down before the other. The top of the trough carries a spring-held arm 100 with rollers 102 to ensure proper contact with the caramel and the sides are similarly provided.

Filed: 1919-05-27
Abstract: 136,464. Mond, A., (International Precipitation Co.). May 27, 1919. Gases, electrically precipitating suspended particles from.-Suspended material is removed from furnace gases and the like by humidification of the gas followed by passage through an electrical precipitator, sufficient cooling taking place either just before or during the passage through the precipitator to ensure the condensation of moisture on the collecting-electrodes. The hot furnace-gases pass by flue 1 into the chamber 2 provided with spraying-devices 12, where they take up water vapour and at the same time have any coarse suspended material washed away. Tho gases may be cooled at this stage by being passed through a chamber 3 fitted with a cooling-device 18, whereby their temperature is reduced sufficiently to condense some of the water vapour. They are then introduced into an electric precipitator of any suitable tvpe, here shown, as comprising a number of collecting-electrodes consisting of vertical pipes 5 in which hang insulated wires 9. The suspended material is deposited upon the electrodes along with the condensed water vapour. The amount of condensation obtained may be sufficient to wash away the precipitate, or only just enough to ensure the conductivity of the deposited material. In any case, it is essential to maintain the deposit at a temperature of not more than 100‹ C. If the gases are not cooled prior to passage through the precipitator, the collecting-electrodes are themselves cooled to a temperature below the dew-point by radiation or by exposure to a current of air from the fan 17, or cool air is admitted by opening the damper 19. When the gases are already sufficiently moist, the passage through the humidifying-chamber 2 may be dispensed with. Specification 119,236 is referred to.
